As usual, I’ve been asking support about this problem every few months. This time I got a different reply that was not copy paste, and they mentioned that if there’s a LOT of similar gigs offered by other sellers, that should be the reason for the drop from first page, and that it would have nothing to do with your gig’s performance.
But they also mentioned that having a gig video helps with this, but personally I have not seen any difference in having one or not having one.
And what confuses me further is that there’s sorting options (Not filters) for gigs just for this reason, so one can find good gigs more easily from the thousands. It’s just that none of the sorting options work in some categories.
Just thought I’d share
